We also want to highlight here that the resolution of the scans within each dataset varies significantly (except for OPIXray [1]}). For example, on GDXray [2]}, the scan resolution varies as \(2688 \times 2208\) , \(900 \times 1430\) , \(850 \times 850\)  and \(601 \times 1241\) , etc. Similarly, on SIXray [3]}, the scan resolution varies as \(681 \times 549 \times 3\) , \(801 \times 482 \times 3\) , \(649 \times 571 \times 3\) , \(1024 \times 640 \times 3\) , and \(675 \times 382 \times 3\) , etc. But on OPIXray [1]}, the resolution of all the scans is 1225x954x3.
In order to process all the scans with the proposed framework, we have re-sized them to the common resolution of \(576 \times 768 \times 3\) , which is extensively used in the recently published frameworks [5]}, [6]}, [7]}.
